So in 19 yrs Earth has a pretty good chance of being clipped round the lug by a giant asteroid,no need to worry about gas bills then as the world will suddenly become very hot, this will of course all take place when "according to sods law," scientists cure the human race of PD , if this collossal piece of rock does choose to visit I hope it makes contact right on top of my house , or even in my rockery , indeed I will sit out in the garden and watch the skies for its approach, knowing my luck it will be cloudy and wet, though not for much longer and even if it misses another is lined up waiting in the depths of our universe to severely dent space ship Earth. a decade or two later , so in the words of Mark Knopfler why worry now.
